It is to be understood that the terminology used in the embodiments of the present invention is for the purpose of describing the particular embodiments, and is not intended to limit the invention. The singular forms "a", "the" and "the" It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

Please refer to FIG. 1. FIG. 1 is a flowchart of an embodiment of an image display method provided by the present invention. An image display method of the present embodiment can be applied to a terminal configured with a rotatable first camera and a rotatable second camera. The first camera and the second camera are located on the same side of the terminal, and the same focal length can be applied to On the terminal, the terminal may be a smart phone, a tablet, etc., and the method includes:

Step S101: adjusting a rotation angle of the first camera and a rotation angle of the second camera.

Specifically, the first camera and the second camera with the same focal length are disposed on the terminal, wherein the first camera and the second camera are located on the same side of the terminal, and both can be rotated by the motor. Generally, when the camera function of the terminal is turned on, the terminal is selected. Entering the wide-angle shooting mode, the terminal enables the first camera and the second camera to adjust the rotation angle of the first camera and the rotation angle of the second camera. The specific adjustment manner may be that the terminal recognizes the target scene according to the content of the target scene. Intelligently adjusting the angle of the first camera and/or the second camera to an optimal rotation angle; or, the terminal receives the input rotation angle of the first camera and the rotation angle of the second camera, according to the input rotation of the first camera The angle and the rotation angle of the second camera, and according to the input rotation angle of the first camera and the rotation angle of the second camera, the motor of the camera is controlled to adjust the angle of the first camera and the angle of the second camera; the terminal may also be configured with Touch screen, specifically adjust the rotation angle of the first camera and the second camera The manner of rotating the angle of the head may also be: acquiring a sliding track or a click position of the input of the user's finger on the touch screen, generating a first camera rotation angle or a rotation angle of the second camera according to the sliding track or the click position, and then controlling the camera motor. Adjust the angle of the first camera and the angle of the second camera.

It should be noted that, assuming that the first camera and the second camera are horizontally disposed, that is, the connection between the first camera optical center and the second camera optical center is in the horizontal direction, the first camera and the second camera may be disposed along the horizontal direction. And rotating in a vertical direction, as shown in FIG. 2, FIG. 2 is a schematic structural diagram of a first camera and a second camera rotating manner according to an embodiment of the present invention; and a direction in which the first camera and the second camera rotate in a vertical direction And the angle is the same, the direction and angle of the rotation in the horizontal direction are not limited; the first camera and the second camera can also be set to rotate only in the horizontal direction, wherein the first camera rotates in the first direction, and the second camera follows the In the two directions of rotation, the first direction and the second direction may be the same or opposite; the maximum rotation angle of the first camera and the maximum rotation angle of the second camera may be set according to the angles of view of the first camera and the second camera, or Setting the maximum angle of the first camera and the second camera, so that the rotation of the first camera is adjusted And a second rotation angle of the camera, the content display content and the second display image of the first image acquisition section adjacent or overlapping.

Step S102: Acquire a first image acquired by the first camera and a second image acquired by the second camera.

Specifically, when the camera function of the terminal is turned on, the user selects to enter the wide-angle shooting mode. At this time, the terminal enables the first camera and the second camera, adjusts the rotation angle of the first camera and the rotation angle of the second camera, and then passes the first camera. The first image is acquired, and the second image is acquired by the second camera at the same time. Since the shooting angles of the first camera and the second camera are different, the first image and the second image they acquire are different.

Specifically, the chrominance component of the pixel of the first image may be Comparing with the chrominance components of the pixels of the second image, determining whether the first image and the second image have overlapping regions, when the chrominance component of the pixel in a certain region of the first image and a certain region of the second image When the chrominance components of the corresponding pixel points are consistent, or when the overlap ratio reaches a preset threshold, determining that the first image and the second image have overlapping regions, the overlapping region being a certain region in the first image and the second image The chrominance component of the corresponding pixel in the domain is consistent or the overlap rate reaches a preset threshold. Similarly, the chrominance component of the pixel in a certain area of the second image is consistent or the overlap rate reaches a preset. The area of the threshold is also an overlapping area. Similarly, the gray component of the pixel of the first image and the gray component of the pixel of the second image may be compared to determine whether the first image and the second image have overlapping regions.

Assuming that the first camera and the second camera are arranged horizontally, that is, the connection between the first camera optical center and the second camera optical center is in the horizontal direction, when the first camera and the second camera are rotatable in the horizontal direction and the vertical direction, and When the direction and the angle of the first camera and the second camera rotating in the vertical direction are the same, the method of comparing the chrominance component of the pixel of the first image with the chrominance component of the pixel of the second image may be referred to FIG. 3 . 3 is a schematic structural diagram of an embodiment of a method for comparing a pixel point of a first image and a pixel point of a second image according to the present invention.
